Your response conveys that you have a fundamental misunderstanding of what the theory even describes. It has not "been predicting overpopulation disaster for 200 years" on a continual basis as you make it seem by your analogy in the second paragraph.
The theory merely maintains that population increases ‘geometrically’ or exponentially and that subsistence increases arithmetically. Thus, population increases along the order of 1, 2, 4, 8, 16, 32..., whereas subsistence limps along at the rate of 1, 2, 3, 4... You are correct that this has been debunked in the past in many ways due to technological and agricultural developments, changes in societal organization.
But it has been revived recently. What you don't take into account is that fact that we are only approaching 7 Billion which is sustainable currently but is expected to double within the next 100 years if not checked. Also, the problem has changed as agriculture is no longer the main concern; Oil and energy are. Peak Oil production has, or will have been reached within the next 10 years which presents an entirely new and much more serious problem for world economies. We are already seeing some of the beginning effects that depletion is having.
Don't get me wrong, I believe humans are ingenious and can move to solve problems when cornered, but I don't think you can argue that at the growth rate we are seeing today, that there will not be any sort of check necessary whether it be natural or imposed by man.
(and i don't think a downvote was necessary, as I was merely stating opinion, as you have as well)
